A piece of copper wire is formed into a single circular loop of radius 11 cm. A magnetic field is oriented parallel to the normal to the loop, and it increases from 0 to 0.65 T in a time of 0.36 s. The wire has a resistance per unit length of 3.1 x 10-2 /m. What is the average electrical energy dissipated in the resistance of the wire?
